  • Patent number: 9215655
    Abstract: In video conferencing over a radio network, the radio equipment is a major power consumer especially in cellular networks such as LTE. In order to reduce the radio power consumption in video conferencing, it is important to introduce an enough radio inactive time. Several types of data buffering and bundling can be employed within a reasonable range of latency that doesn't significantly disrupt the real-time nature of video conferencing. In addition, the data transmission can be synchronized to the data reception in a controlled manner, which can result in an even longer radio inactive time and thus take advantage of radio power saving modes such as LTE C-DRX.

  • Publication number: 20150341255
    Abstract: Disclosed is a multi-domain routing computation method, including: when it is determined that there are two or more domains deployed with a Path Computation Elements (PCE) in a network, a routing path is computed, between a PCE of a first domain and a PCE of a last domain among the two or more domains deployed with a PCE, using an extended Backward-Recursive PCE-Based Computation (BRPC) algorithm, and the routing path is computed using a Routing Controller (RC) in domains other than the two or more domains deployed with a PCE. Further disclosed are a multi-domain routing computation device, a path computation element and a routing network. The present disclosure can improve greatly optimality of path computation and has a fairly high efficiency for the path computation.

  • Publication number: 20150277772
    Abstract: A global memory sharing method includes counting, by the sub-operating system, a page replacement rate in a task scheduling period of a predetermined quantity of times, and a memory residence time ratio in a page replacement period; calculating, by the sub-operating system, a memory pressure index according to the page replacement rate and the memory residence time ratio; and if the memory pressure index is greater than a memory pressure threshold, sending, by the sub-operating system, an application to a global memory management service module. According to the forgoing method, in an architecture of multiple operating systems, each sub-operating system can complete much adaptive work, which reduces complexity of the global memory management service module and improves system performance. Meanwhile, a utilization rate of global memory may be improved, and the architecture of the multiple operating systems may have better extensibility.

  • Patent number: 9042904
    Abstract: Techniques for localized dynamic channel allocation help meet the challenges of latency, memory size, and channel time optimization for wireless communication systems. As examples, advanced communication standards, such as the WiGig standard, may support wireless docking station capability and wireless streaming of high definition video content between transmitting and receiving stations, or engage in other very high throughput tasks. The techniques help to deliver the desired user experience in such an environment and support desired performance levels for latency and throughput while controlling memory footprint.

  • Patent number: 9036478
    Abstract: Techniques for securing transmit opening help enhance the operation of a station that employs the technique. The techniques may facilitate low latency response to a protocol data requester, for instance. The techniques provide ways for the protocol data requester to provide additional time for the protocol data responder to obtain the needed response data for the protocol data requester. One way in which this can be done is by intelligently lengthing the protocol request transmitted by the protocol requester.

  • Publication number: 20150095506
    Abstract: Disclosed are a path computation element communication protocol (PCEP) session establishment method and device. The technical solution comprises: at a PCC or PCE node device side, before needing to establish a PCEP session, allocating a TCP connection communication end attribute to a PCC or a PCE at either end in the manner of static configuration/dynamic designation or election mechanism automatic allocation; or detecting whether to establish a TCP connection relationship, if not, actively connecting the opposite end, and if a plurality of TCP connection relationships has been established, simultaneously cutting off a plurality of connections at both ends, and reinitiating a TCP connection after waiting a random time respectively. The present invention achieves the establishment of a PCEP session in the multi-PCE cooperation computation scenario under the condition of meeting two constraint conditions which are specified by a protocol.

  • Patent number: 8755318
    Abstract: Synchronizing uplink and downlink transmissions by a wireless user equipment (UE) device. A connection with a network may be established via a wireless link with a cell. The UE may operate in an active state during first periods of time in which uplink or downlink communications may be performed between the UE and the network. The UE may operate in a reduced-power state during second periods of time in which uplink and downlink communications are not performed. The first periods of time may alternate with the second periods of time in a repeating manner. Uplink data generated by the UE may be buffered during second periods of time and transmitted during first periods of time. Buffering uplink data in this manner may prevent the UE from immediately transitioning from the reduced-power state to the active state to transmit uplink data, which may conserve battery of the UE.

  • Patent number: 8694250
    Abstract: Computer-implemented methods and apparatus are presented for processing data collected by at least two receivers from multiple satellites of multiple Global Navigation Satellite Systems (GNSS), where at least one GNSS is Frequency Division Multiple Access (FDMA). Data sets are obtained which comprise a first data set from a first receiver and a second data set from a second receiver. The first data set comprises a first FDMA data set and the second data set comprises a second FDMA data set. At least one of a code bias and a phase bias may exist between the first FDMA data set and the second FDMA data set. At least one receiver-type bias is determined, to be applied when the data sets are obtained from receivers of different types. The data sets are processed, based on the at least one receiver-type bias, to estimate carrier floating-point ambiguities. Carrier integer ambiguities are determined from the floating-point ambiguities.
